  • Not really hacking, but in the 90s you could usually just connect to a mail server and it would believe what you told it.

    If you were careful you could just type an email directly: MAIL FROM, RCPT TO, etc.

    I would write scripts at work to send spoof emails sometimes, you could put anything as the FROM address, like “info @ catfacts” or whatever.

    Another “not really hacking” example is that when some companies first got an Internet connection, they would just allocate public IP addresses to everyone, no gateway or firewall. So you could browse any non-passworded smb shares just knowing the IP.













  • I see I misunderstood how you mean this to work, that routing would handle sending data only to subscribers. I was imagining that it mean a simple LAN broadcast using a packet with the subnet bits all set (e.g. 192.168.255.255). I think that it’s more analogous to a mailing list distribution, but for general data/streams?

    But your earlier example of downloading the cat video still fails unless many people request the video at the same time (otherwise you’re multicasting to one). What happens if I watch the video on my phone while out, then watch it again on my laptop at home? It will still need sending twice.

    Wouldn’t a more efficient approach just be to have something like ipfs with lots of local caching?


  • I don’t see how that would work. So all my friends video streams, for instance, would be streaming data to all my devices as they are broadcast.

    But my laptop is currently asleep. It wouldn’t receive anything.

    How do you solve that without storing the video on a server that I can pull from on demand?

    Even for my devices that are on, they’d have to store everything as it was broadcast.

    And the streams (including every other broadcast) would constantly be eating up my bandwidth.

    How would I not receive streams that I’m not interested in? What would decide which broadcast packets do or don’t get sent to my router?
